Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic power generation, in particular to a floating bridge type hydraulic power generation device. Background Technique

[0002] The basic principle of hydraulic power generation is a process of converting the energy of water flow or water head energy into mechanical energy by using the energy of water flow, and then converting the mechanical energy into electrical energy through a water turbine. The basic principle of hydraulic power generation is to utilize the water flow with potential energy located at a high place such as a river or a lake to flow to a low place, and cooperate with a water turbine generator to generate electricity. Specifically, the water body with higher potential energy enters the runner channel of the water turbine through a pressure pipeline or a pressure tunnel or directly enters the water turbine. The runner of the water turbine rotates under the impact of the water flow, converting the water energy into mechanical energy. The runner of the water turbine drives the coaxial generator to rotate. The magnetic force lines of the magnetic field generated by the rotor winding are cut by the stator of the generator, converting the mechanical energy into electrical energy. The generated electricity is connected to the power system through a step-up transformer and sent to the power grid.

[0003] Hydraulic power generation usually requires building a dam to intercept water and then building hydraulic power generation facilities on this basis, which has problems such as high cost and long construction period. Moreover, the river flow velocity in many mountainous areas is very fast and the elevation difference is large. Due to environmental and geological reasons, dams cannot be built to store water for power generation with conventional power generation equipment, and the energy cannot be fully utilized. Therefore, we propose a floating bridge type hydraulic power generation device. Content of the Utility Model
